IMPROVEMENT IN SWINGS.

Specification forming part of Letters Patent No. 191,683,

dated June 5, 1877 application filed May 12, 1877.

To all whom it may concern Be it known that I, JOHN J. JANEZECK, ofWashington, in the county of Washington and District of Columbia, haveinvented certain new and useful Improvements in Swings; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to improvements in that class of swings which areset and mainsists in the construction and arrangement of the variousparts, as hereinafter described and claimed, whereby the swing may bereadily adjusted for the use of a child or adult, being worked with thegreatest ease by a gentle pulling and pushing motion, alternately, thusfurnishin g a graceful and wholesome exercise similar to rowing.

Figure 1 is a perspective view of my improved swing; and Fig. 2 is avertical side elevation of the same, partly in section.

The supporting-frame of the swing consists of two standards, A A,resting upon a quadrangular foundation-frame, and connected at the topby a cross-beam, B, suitable braces being provided to insure strength. 0O are the hanging rods, two on each side, which are suspended in anyappropriate and safe manner from the cross-beam B, so that the inner orrear rods 0 are attached in front of the outer or forward rods 0, thetwo rods on each side thus crossing each other near their upper ends.These hanging'rods support the chair D, which is secured to their lowerends by suitable pivot-bolts. Motion is imparted to the chair D by meansof the levers e g and links f h on each side, the rear hanging rods 0also acting as additional levers. The levers e and g are pivoted, at ornear their lower ends, to the chair-frame, and are connected by the linkf, the lever g being also connected with the rear hanging rod or lever Gby means of the link h. A hand-bar, t, extends across the front of thechair from the upper end of the lever g on one side to the correspondinglever on the opposite side,

and a foot-bar, It, extends from the forward end of the link fto a likepoint on the opposite link.

In starting the swing, the occupant should pull gently on the hand-bari, at the same time pressing with the feet upon the foot-bar is, thussecuring the benefits of adouble leverage, which throws the upper end ofthe lever g backward, its lower end moving forward, assisted by thepressure of the feet upon the foot-bar k, and carrying with it thelinkfand lever 0, attached thereto, so as to force backward the chair D.As the chair returns to a perpendicular position the occupant pushes onthe. hand-bar i and slacks the pressure on the foot-bar It, thus forcingforward the upper end of the lever g, which carries its lower endbackward, drawing with it the link fand upper end of the lever 6, so asto carry the chair forward.

By means of the link It, connecting the lever g with the rear hangingrod U, the latter is also converted into a lever, as before stated, andthe leverage is thus distributed throughout the chair-frame, producing asteady and equable motion, and preventing any undue strain. This effectis further increased by the manner of crossing the hanging rods 0 0 neartheir upper ends, and by the employment of the cross brace m, connectingthe two rear rods or levers C, which construction allows the hangingrods a wide range of oscillation without danger of their snapping orstraining, and without liability to jar in the back and forward motionof the chair.

Thus by alternately pulling and pushing upon the hand-bar 21. togetherwith a slight pressure of the feet upon the foot-bar k as the chairrecedes, the swing may be easily maintained in motion by the occupantwithout requiring any unusual exertion, and causing much less fatiguethan that involved in rowing a boat, which exercise it resembles. Byapplying the power in a direction contrary to that required for thepurpose of operating the swing, the hand-bar iand attached levers willact as brakes to suspend its oscillation.

The swing, constructed as described, is capable of ready adjustment tomeet the wants of children or adults using it, the various levers, bars,and rods employed in its propul- DISTRIOT OF COLUMBIA, ASSIGNOR sionbeing provided with suitable holes or re- I cesses, by which they may bearranged and pivoted with relation to each other, so as to increase ordiminish the leverage to suit the weight and power of the occupant. Asthe chair, when at rest, is only a few inches from the ground, easyaccess is aii'orded for children, and the hand-bar, properly arranged inplace, will prevent them from falling out when the swing is in motion.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with the frame A B and. hanging rods 0 O, crossed neartheir tops, and connected by the brace m, of the chair D,

provided with the levers e g, linksf h, and bars JOHN J. JANEZEGK.
